'Don't clean coins".
If acetone won't remove the black stuff, it is most probably INorganic.
If you want to remove the black stuff it seems that the only way of doing so with minimal damage, is to chemically clean it with one of the commercial non abrasive silver cleaners, unfortunately.
If you do that, ALL of the coin is going to be affected. It may end up looking better but such cleaning certainly will not increase the value.

I think that the black is back because it's been 18 months since he cleaned it and answered the previous posts. Silver is a pretty active element so the black could be anything and probably not anything that was applied or spilled.

thanks all
would anyone know if the
acetone in nail polish
would take off paint ?
that is what was used. ?
may not be strong enough for
some paints or felt pens etc.
do you think it worth while
finding another solvent or use
acetone once again
it looks as if etched by acid? maybe ?
regards

I still think you should use it as a pocket piece, it will wear away the black over time as well as the old cleaning.
Feel free to call me Will.

I have encountered a few Sellers on ebay that would take a Dremel polisher to that coin and then list it as a "high-grade, nice original luster" coin! |

I'm just coming into this discussion, but seeing the pictures I at least suspect that the black areas on both sides are heavy tarnish and the silver areas are covered with clear paint, perhaps lacquer. Dipping the coin (or test rubbing the black with a Q-tip dipped in coin dip) should answer the question about the black. Lacquer remover will deal with any lacquer, though use it in a well-ventilated area to minimize inhalation of the toxic fumes.

I left this coin
in acetone overnight
and it is still the same.
would that rule out paint
or magic marker. ?
I did not rub or swab it.
just hoped the acetone would dissolve
the blemish.
may I ask for other suggestions/ideas
regards

Looks like some sort of oxide or corrosion on the coin... I think it is unremovable, without seriously damaging the coin...

AS JHax said soak in LACQUER thinner not acetone. If this does not work, I have a theory that this could be one of those PLATED jobs that were prevalent in the 1960 and 1970 period. You have probably seen the odd one in an ICCS flip with "Silver Wash " in the comments section. Your coin may have been fully blackened due to enviro problems or even have been in a fire . Sad part the coin is not of a high enough value to send to a conservation service. Would cost you way too much to get it fixed. If it were mine I would sell it for whatever and put the money to a nice MS63. Good luck.
